MBR140SF

Shikues · Schottky Diodes · SOD-123

MBR140SF from Shikues, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the Schottky diode, the end marked with the polarity band on the case; VRRM/VR is 40 V and VF is 0.6 V max at IF=1 A.
2 A passive Anode of the Schottky diode; average rectified output current IO is 1 A and peak forward surge current IFSM is 25 A (8.3 ms).

CAD (KiCad official)

  • Symbol: MBR140SF
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mbr140sf-etched.step / mbr140sf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mbr140sf.step / mbr140sf.glb are the bare package body.
